Ubisoft have announced that later today, they will be live streaming some gameplay footage for Rainbow Six: Siege from the Closed Alpha for PC on their Twitch Channel. While, there are no details about which maps or options will be shown during the livestream, they did reveal that it will start at 11:00 AM PST / 2:00 PM EST / 7:00 PM BST / 8:00 PM CET.

Its funny how you say "Ubisoft-it" up. IMO the only bad games they have released was Watch Dogs and AC Unity. They are actually incredibly talented developers who have developed many great franchises including Rainbow Six. They don't muck up half as many games as Activision.
